Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details.

It should be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In order to monitor the hydrogen concentration in the working environment, it is generally necessary to detect the volume fraction of hydrogen (hydrogen concentration) in the air in real time or at fixed intervals by using a detection device such as a hydrogen detector. And then, alarming when the hydrogen concentration is detected to be larger than the early warning concentration.
Specifically, the hydrogen detector can detect the hydrogen concentration in the air, convert the hydrogen concentration into an electric signal and then transmit the electric signal to the alarm controller through a cable. The hydrogen concentration is higher, the electric signal is stronger, and when the hydrogen concentration reaches or exceeds the early warning concentration set by the alarm controller, the alarm controller can send out an alarm signal to control the alarm equipment to perform early warning.
However, when the alarm device is controlled to perform early warning, a serious hydrogen leakage event may occur in the working environment, so that the hydrogen concentration in the closed space is higher, and a larger safety risk is provided. If the early warning concentration is set to be low, the hydrogen detector can frequently control the alarm equipment to perform early warning, and the operation is influenced.
Based on this, in order to reasonably early warn the change of the hydrogen concentration, the embodiment of the application provides a hydrogen concentration early warning method, which can be applied to terminal devices such as a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook and the like, or can be applied to detection devices such as a hydrogen detector and the like, and the embodiment of the application does not limit the specific type of the terminal devices.
Referring to fig. 1, fig. 1 shows a flowchart of implementation of a hydrogen concentration early warning method according to an embodiment of the present application, where the method includes the following steps:
s101, respectively acquiring a first concentration of hydrogen detected by each detection device and a second concentration detected last time.
In an embodiment, the detecting device is a device for detecting a hydrogen concentration in air. The detection equipment can be a portable hydrogen detector, a pumping type hydrogen detector, an online hydrogen detector and other types. The plurality of detection devices may be the same type of detector, or may be different types of detectors, which is not limited.
The plurality of detection devices can be arranged around the storage device for storing hydrogen, so that the hydrogen leakage event of the storage tank can be timely detected by the detection devices.
In an embodiment, the first concentration is a concentration of the hydrogen gas detected by the detecting device at the current time. The second concentration is the concentration of the hydrogen gas detected by the detecting device at the previous time. In general, the detection device may detect the hydrogen concentration once every fixed period.
S102, determining target detection equipment from all detection equipment according to the first concentration and the second concentration respectively.
In an embodiment, based on the above description of the detecting apparatus, if the target concentration change result of the hydrogen is determined according to all detecting apparatuses, the change between the first concentration and the second concentration detected by the detecting apparatus at a position farther from the leaking position may be smaller due to the difference between the leaking position of the storage device and the detecting apparatus. Further, when the target concentration change result is determined according to all the detecting apparatuses later, it may be considered that the storage device is not leaked at this time until when the target concentration change result is determined according to all the detecting apparatuses that the concentration of the hydrogen is greater than the preset concentration, the storage device may have leaked more hydrogen at this time, with a great risk.
Therefore, it can be considered that the target detection apparatus is determined from all the detection apparatuses, and the target concentration variation result is determined based on the first target concentration and the second target concentration detected by the target detection apparatus later, and the reliability of the target concentration variation result can be improved.
Specifically, for any detection device, the terminal device may calculate a difference between the first concentration and the second concentration; and if the difference is larger than the preset value, the detection equipment is considered to be close to the leakage position in the storage device. Thus, the detection device can be determined as the target detection device. Otherwise, when the difference is less than or equal to the preset value, the detection device may be considered to be farther from the leak location.
It should be noted that, when the difference between the first concentration and the second concentration corresponding to all the detection devices is less than or equal to the preset value, it may be considered that the storage device is not leaked. Therefore, the terminal device does not need to perform the subsequent steps S103-S104.
In an embodiment, the preset value may be set according to practical situations, which is not limited.
Wherein determining whether the detection device is the target detection device is only one example thereof based on the difference being greater than a preset value. In another embodiment, the terminal device may further acquire an image including the storage device acquired by the image acquisition device, and perform image recognition on the image to determine whether the storage device has a leak. Thereafter, when it is determined that the storage device has a leak, a leak position is determined from the image. Finally, the terminal device may determine, as target detection devices, all detection devices within a preset distance from the leakage position.
It should be added that, the mode of image recognition may be that a trained recognition model is preset in the terminal device, and the trained recognition model may perform model processing on the image to output a recognition result. The identification result is divided into a result that the storage device is not leaked and a result that the storage device is leaked and contains a specific leakage position.
S103, predicting a target concentration change result of the hydrogen after the preset time according to the first target concentration detected by all the target detection devices and the second target concentration detected by the target detection devices last time.
In an embodiment, the preset time may be set according to actual situations. Generally, if the concentration of the hydrogen is predicted to be greater than or equal to the preset concentration after the preset time, an early warning instruction can be sent to the alarm device to control the alarm device to alarm. The staff may then react to this leak event in a targeted manner within a preset time. That is, it can be considered that the preset time should be greater than or equal to the processing time during which the worker can make the targeted operation.
The target concentration change result is divided into a result that the concentration of the hydrogen is greater than or equal to the preset concentration after the preset time and a result that the concentration of the hydrogen is less than the preset concentration after the preset time. Wherein, because the volume fraction of hydrogen in the air is between 4% and 75%, explosion is very easy to occur, and therefore, the preset concentration can be 4%.
In an embodiment, the first target concentration may be a first concentration of hydrogen detected by the target detection device at the current time; the second target concentration may be the second concentration of hydrogen gas that the target detection apparatus detected last time.
It is to be noted that, as is clear from the explanation of S102, the number of the specified target detection apparatuses may be 1 or more, because the leak positions in the storage device are different from each other. Based on this, at 1, the target concentration variation result can be determined directly from the first target concentration and the second target concentration of the target detection apparatus.
However, when the number of target detection apparatuses is plural, the first target concentration and the second target concentration, which are detected by each target detection apparatus, may be different from each other, also because the distance of the leak position in the storage device is different. Thus, the initial concentration variation results ultimately predicted for the different first and second target concentrations will also be different.
Based on this, for any target detection device, the terminal device may determine an initial concentration change result of the hydrogen after the preset time according to the first target concentration and the second target concentration. And then, counting all initial concentration change results to be a first quantity that the concentration of the hydrogen is greater than or equal to the preset concentration after the preset time. Finally, a target concentration variation result is determined from the first quantity.
The initial concentration change result is also divided into a result that the concentration of hydrogen is greater than or equal to the preset concentration after the preset time and a result that the concentration of hydrogen is less than the preset concentration after the preset time.
Specifically, the terminal device may first calculate the concentration change rate of the hydrogen gas in the unit time according to the first target concentration and the second target concentration. Then, the terminal device may calculate a product value of the concentration change rate and the preset time as the concentration of the hydrogen gas increased in the preset time. Finally, the sum of the product value and the first target concentration is determined as the concentration of hydrogen after a preset time. At this time, the terminal device may directly determine the initial concentration variation result according to the concentration of the hydrogen after the preset time and the preset concentration.
For example, the terminal device may first calculate a concentration difference between the first target concentration and the second target concentration, and determine a time difference between the current time and the time at which the second target concentration was last detected. Then, the ratio of the concentration difference to the time difference is determined as the concentration change rate of the hydrogen gas at the future time. I.e., the rate at which the storage device leaks hydrogen. Wherein the hydrogen concentration is typically detected once per fixed period as the detection device. Thus, the time difference is typically one cycle.
It will be appreciated that the first target concentration and the second target concentration for different target detection devices are different and, therefore, their respective rates of change of concentration are also typically different.
In an embodiment, the determining the target concentration change result according to the first number may be: counting the second quantity of all initial concentration change results; if the ratio of the first quantity to the second quantity is larger than or equal to the preset ratio, determining that the concentration of the hydrogen is larger than or equal to the preset concentration after the target concentration change result is the preset time; if the ratio of the first quantity to the second quantity is smaller than the preset ratio, determining that the concentration of the hydrogen is smaller than the preset concentration after the target concentration is changed for the preset time.
The preset ratio can be set according to actual conditions, and in order to timely find whether the storage device has a leakage event or not, and avoid frequent alarm generation caused by false detection, for example. The ratio may be 0.5. Wherein, set up the purpose that preset ratio is 0.5: if the preset ratio is small, an alarm may be frequently generated due to the presence of false detection of the target detection device, and if the preset ratio is large, it may be difficult to generate an alarm in time when a leakage event occurs.
And S104, if the target concentration change result is that the concentration of the hydrogen is greater than or equal to the preset concentration after the preset time, sending an early warning instruction to the alarm equipment.
In an embodiment, when the target concentration change result is that the concentration of the hydrogen is greater than or equal to the preset concentration after the preset time, in order to avoid danger, the terminal device may generate an early warning instruction to the alarm device in advance, so as to control the alarm device to early warn the staff. When the target concentration change result is that the concentration of the hydrogen is smaller than the preset concentration after the preset time, the storage device can be considered that no leakage event occurs, so that the terminal equipment can execute the hydrogen concentration early warning method again.
In another embodiment, the concentration of hydrogen is greater than or equal to a preset concentration after the target concentration change result is determined to be a preset time, in order to enable a worker to determine the emergency degree of hydrogen leakage to process it in a targeted manner. The terminal device may further determine a concentration change rate maximum value from all concentration change rates after calculating the concentration change rates of the hydrogen gas corresponding to each target detection device, respectively, in unit time. Meanwhile, a first target concentration maximum value is determined from the first target concentrations detected at all the present moments. Then, a concentration difference between the preset concentration and a first target concentration maximum is calculated. And finally, determining the ratio of the concentration difference value to the maximum value of the concentration change rate as the target duration required by the concentration of the hydrogen to be greater than or equal to the preset concentration when the storage device has a leakage event.
Then, the terminal device can determine a target time period in which the target duration is located and a target emergency degree corresponding to the target time period according to the association relation between the preset emergency degree and the time period. And then, sending a target early warning instruction corresponding to the target emergency degree to the warning equipment so as to control the warning equipment to perform early warning according to an early warning mode corresponding to the target early warning instruction.
The early warning mode comprises one or more modes including, but not limited to, whistling, flashing, voice broadcasting and the like. The degree of urgency may be categorized as mild, moderate, and severe. Illustratively, the shorter the time period, the faster the concentration of hydrogen will reach the preset concentration, and therefore, the higher the degree of urgency the shorter the time period corresponds to. At this time, the early warning mode corresponding to the shorter time period can be a combination of three modes of whistling, flashing and voice broadcasting.
In this embodiment, in order to improve the reliability of the predicted target concentration variation result, the terminal device may detect the concentration of hydrogen gas according to a plurality of detection devices. And then, further determining target detection equipment with higher detection precision from all detection equipment according to the first concentration detected by each detection equipment and the second concentration detected last time, and predicting a target concentration change result of the hydrogen after preset time according to the first target concentration detected by all the target detection equipment and the second target concentration detected last time. With this, the reliability of the predicted target concentration variation result can be further improved. And finally, when the target concentration change result is that the concentration of the hydrogen is greater than or equal to the preset concentration after the preset time, an early warning instruction can be timely sent to the alarm equipment so as to reasonably early warn the change of the concentration of the hydrogen.
In another embodiment, after determining the target detection device, in order to avoid that the first concentration detected by the target detection device has an error, the terminal device may further correct the first concentration to obtain the first target concentration with higher accuracy.
Specifically, the terminal device may acquire a current environmental factor located in a preset range of the target detection device, and determine a target correction coefficient corresponding to the current environmental factor according to an association relationship between the preset environmental factor and the correction coefficient. And finally, correcting the first concentration by adopting a target correction coefficient to obtain a first target concentration. For example, a product of the target correction coefficient and the first concentration is determined as the first target concentration.
The current environmental factors include, but are not limited to, temperature, air pressure, humidity, and the like. In general, the first concentration of hydrogen gas detected by the detection device may differ under different environmental factors. That is, the detection device may be highly susceptible to temperature, air pressure, and/or humidity such that the detected first concentration has errors.
The preset range can be set according to actual conditions. Illustratively, because the storage device storing hydrogen is typically located within the enclosed space, however, the temperature, pressure, humidity, etc. within the enclosed space are typically consistent. Therefore, the preset range can be considered as a range corresponding to the entire enclosed space.
Wherein, different environmental factors can be acquired according to different acquisition devices. For example, acquisition devices such as temperature sensors, humidity sensors, barometers, etc., are acquired and will not be described in detail.
Based on the above, the terminal device may simulate a plurality of environmental factors in advance, and acquire a concentration value of the detection device for collecting the concentration of the hydrogen under each environmental factor. And then, determining a corresponding correction coefficient according to the actual concentration value of the hydrogen under each simulated environmental factor. And then, establishing an association relation between the preset environmental factors and the correction coefficients.
In a specific embodiment, when determining the corresponding correction coefficient according to the actual concentration value of the hydrogen under each simulated environmental factor, the detection device may acquire the concentration of the hydrogen multiple times under the same environmental factor, so as to obtain multiple concentration values. Then, a ratio of the actual concentration value to the average value of the plurality of concentration values is determined as a correction coefficient.
